Hi everyone:
Every time I export the audio, the resulting file has a fade in of less than a second but enough to perceive, this is not the case with the Concrete Limiter or another limiter. I was already playing with the parameters and I have not found a solution.
Greetings.

Try reducing the Lookahead to minimum?

There's a second thread about issues with the Adaptive Limiter. They may not be related at all to your export issue, but you never know.
 
For me, I found that having the 64-bit Double Precision Engine checked in Preferences/Audio/Driver Settings caused problems during playback. Since that function is also available in the Export options, you may want to check if you have it enabled, and if so, try disabling it to see if that makes a difference.

Yes Mr. Anderton, I have reduced the Lookahead, I have changed the parameters, I have used the presets and it continues to have the same performance, casually listening to the session is correct, it only happens when exporting, attach some audio samples for a better understanding of the problem.

Yes ptheisen, I have disabled the 64-bit double precision engine.

Thank you.
